I agree this is important, the only thing would be whether it can be shown to be an active ingredient - even without explicitly stating and disconfirming it, expectancies are likely to be activated and contradicted.

NA
Expectancies for aversive events are explicitly stated before the start of the exposure trial and monitored throughout the exposure trial (perhaps better called expectancy monitoring)

I would use another term than consolidation as this also refers to the process of memory storage/stabilisation that is also often spoken of in fear learning/extinction.

NA
Could also be stated as ‘prediction error’. It’s a little difficult whether the expectancy violation should be ‘reduced to a certain level’, or whether it is instead a binary thing: you make the explicit and specific prediction and test it in the exposure. Could expectancy statement and expectancy violation even be combined to refer to a ‘behavioral test’ - as in CBT where the cognitions/expectations are treated as a hypothesis and the exposure functions as a behavioral test of them

corrections_overestimation
dit is 1 kant van angst; de andere is de mate waarin iemand zelfvertrouwen (self-efficacy; problem solving/coping) heeft een probleem aan te kunnen (CBT kan zich ook op die kant richten om angst te verminderen)
It would depend on when this occurs: if exposure therapy works by forcing a prediction error to update beliefs, then some theorists would say that lessening overestimation before exposure would be counterproductive, as it would lessen the contrast between what is expected and what occurs, and reduce inhibitory learning.
The formulation is somewhat obscure. What exactly is the intervention?

Could also have a separate thing for enhancing extinction learning with pharmacological means? The same could go for habituation (a drug taken to reduce arousal during exposure could make habituation more rapid).

I would say ‘retrieval-extinction’ rather than reconsolidation. I the one case, you simply state what is occurring (brief retrieval, then extinction), whereas in the other a specific process is inferred. There is a lot of conflicting evidence about whether retrieval-extinction procedures are really reconsolidation-based.

omissions
- Mogelijk nog het aantal behandelingen.
En waarschijnlijk ook goed om onderscheid te maken in typen angst: bijvoorbeeld in termen van complexiteit (bijv. spinnenangst vs. sociale angst).
- One of the things I thought of was that sometimes a pharmacological agent is used to enhance inhibitory learning. Perhaps: ‘pharmacological enhancement’ or something like that.
The reference to reconsolidation is questionable as I noted above, in that we do not know whether reconsolidation is what is occurring. Also though, if a reconsolidation approach is taken and reconsolidation is what is believed to be happening, then it would be neither a habituation nor an inhibitory learning approach. The idea that people focusing on reconsolidation in exposure are pushing is that rather than inhibitory memories being formed, the original memory is directly updated.
No
- self-efficacy (Bandura)
contingency management (rewarding courageous behaviors (by praise or material rewards by therapist and carers; self-reward; ignoring anxious behaviors)
It’s maybe implicitly stated in the ‘fear monitoring’ ingredient, but I would add ‘fear eliciting’: one needs to be sure the participant is feeling anxious/experiencing fear in order for habituation to be possible

JabRef configuration
When opening a bibliographic library (i.e. a file with the extension .bib) in JabRef, it will show the entry table, which is a convenient way to inspect all entries (hits, references, articles, etc) in the library. To prepare JabRef for screening, two settings are important.
First, to change the fields that are visible in the overview table of all references (i.e. the entry table), open the ‘Options’ drop-down menu and select ‘Preferences’. In the preferences dialog, open the ‘Entry table columns’ section:
Figure 1: Screenshot of JabRef preferences dialog when the ‘Entry table columns’ section is opened.
There, the columns shown in the entry table can be edited in the ‘Entry table columns’ sections. A bit confusingly, this is done by adding rows in the table shown in this dialog. Each ‘row’ in this table represents a column in the entry table.
Note that in bibtex (and therefore JabRef), you can create new fields on the fly. In this case, use field ‘screening1’ for screening the hits of this first screening iteration: simply add this field name as a ‘row’ (column) in the entry table. This will show, for every entry, the contents of that field (if it has any).
Second, you need to be able to edit the content in that field. The entry table is very convenient to maintain an overview of the entries in the database, but cannot be used for editing. To edit an entry, double click it in the entry tabel. This opens the entry editor, which has a number of tabs. Each tab shows a number of fields which can then be edited.
These tabs can be configured by setting the ‘General fields’. Open the ‘Options’ drop-down menu and select ‘General Fields’ to configure which fields are available in the different tabs when opening an entry.
Figure 2: Screenshot of JabRef dialog used to set the general fields.
Add a dedicated field for the reviewing, showing only the title, abstract, and screening1 fields. This allows you to focus on the relevant information while ignoring irrelevant and potentially biasing information (such as year, journal, and authors). Each row in this text area shows one tab. The first term on each row is the tab’s name, followed by a colon (:) and then the fields shown in the tab, separated by semicolons (;). For example, you could add the following row:
Screening Round 1:title;abstract;screening1
Screening process
For every entry, add the following text in the ‘screening’ field:
- If it is excluded, add the reason, specifically (these are ordered progressively; i.e. if one of the criteria matches, apply it and move on to the next entry):
duplif the study is a duplicate of another entry;noexperif the study does not have an experimental design;nopopulif the study did not sample participants younger than 18 years;noexposif the study did not compare two groups that differ in the treatment in terms of exposure as a part of cognitive behavioral therapy;nophobiaif the study did not concern treatment for phobia disorders;
- If it is included, add
incl.
So once JabRef is opened, when screening, make sure that the ‘screening1’ field is shown in the entry table (i.e. that it is one of the entry table columns), and create one entry editing tab using ‘General Fields’ that contains the fields title, abstract, and screening1. You can then use this tab for the screening. It is also convenient to show field dupl in either the entry table or the screening tab in the entry editor, because for duplicate records (that were identified as such - the algorithm may miss some duplicates of course), that field contains the text dupl.
Make sure to save the database with query hits under a different name than 2018-08-28-screening.bib. That is important because file 2018-08-28-screening.bib will get overwritten if this R Markdown file is executed again. This file will not require any adjustments if you name the database 2018-08-28-screened.bib.

Psychological Trauma: Theory, Research, Practice, and Policy. 10.1037/tra0000190
Objective: The 1-year outcome and moderators of adjustment for children and youth receiving treatment for posttraumatic stress disorder (PTSD) following single-incident trauma was examined. Method: Children and youth who had experienced single-incident trauma (N = 33; 7–17 years old) were randomly assigned to receive 9 weeks of either trauma-focused cognitive behavior therapy (CBT) or trauma-focused cognitive therapy (without exposure; CT) that was administered to them and their parents individually. Results: Intent-to-treat analyses demonstrated that both groups maintained posttreatment gains in PTSD, depression and general anxiety symptoms reductions at 1-year follow-up, with no children meeting criteria for PTSD. A large proportion of children showed good end-state functioning at follow-up (CBT: 65%; CT: 71%). Contrary to 6-month outcomes, maternal adjustment no longer moderated children’s outcome, nor did any other tested variables. Conclusion: The findings confirm the positive longer-term outcomes of using trauma-focused cognitive–behavioral methods for PTSD secondary to single-incident trauma and that these outcomes are not dependent on the use of exposure.

Journal of Autism and Developmental Disorders. 10.1007/s10803-009-0791-7
This pilot study tested the effect of cognitive behavioral therapy (CBT) on parent-reported autism symptoms. Nineteen children with autism spectrum disorders and an anxiety disorder (7–11 years old) were randomly assigned to 16 sessions of CBT or a wait list condition. The CBT program emphasized in vivo exposure supported by parent training and school consultation to promote social communication and emotion regulation skills. Parents completed a standardized autism symptom checklist at baseline and posttreatment/ postwaitlist and 3-month follow-up assessments. CBT outperformed the wait list condition at posttreatment/postwaitlist on total parent-reported autism symptoms (Cohen’s d effect size = .77). Treatment gains were maintained at 3-month follow-up. Further investigation of this intervention modality with larger samples and broader outcome measures appears to be indicated. (PsycINFO Database Record (c) 2016 APA, all rights reserved)

Cognitive-behavioral theory and empirical support suggest that optimal activation of fear is a critical component for successful exposure treatment. Using this theory, we developed coding methodology for measuring CBT-specific process during exposure. We piloted this methodology in a sample of young children (N = 18) who previously received CBT as part of a randomized controlled trial. Results supported the preliminary reliability and predictive validity of coding variables with 12 weeks and 3 months treatment outcome data, generally showing results consistent with CBT theory. However, given our limited and restricted sample, additional testing is warranted. Measurement of CBT-specific process using this methodology may have implications for understanding mechanism of change in exposure-based treatments and for improving dissemination efforts through identification of therapist behaviors associated with improved outcome.

(2015/01//) Cognitive behavioral therapy for early adolescents with autism spectrum disorders and clinical anxiety: A randomized, controlled trial.. Behavior Therapy. 10.1016/j.beth.2014.01.002
Clinically elevated anxiety is a common, impairing feature of autism spectrum disorders (ASD). A modular CBT program designed for preteens with ASD, Behavioral Interventions for Anxiety in Children with Autism (BIACA; Wood et al., 2009) was enhanced and modified to address the developmental needs of early adolescents with ASD and clinical anxiety. Thirty-three adolescents (11–15years old) were randomly assigned to 16 sessions of CBT or an equivalent waitlist period. The CBT model emphasized exposure, challenging irrational beliefs, and behavioral supports provided by caregivers, as well as numerous ASD-specific treatment elements. Independent evaluators, parents, and adolescents rated symptom severity at baseline and posttreatment/postwaitlist. In intent-to-treat analyses, the CBT group outperformed the waitlist group on independent evaluators’ ratings of anxiety severity on the Pediatric Anxiety Rating Scale (PARS) and 79% of the CBT group met Clinical Global Impressions–Improvement scale criteria for positive treatment response at posttreatment, as compared to only 28.6% of the waitlist group. Group differences were not found for diagnostic remission or questionnaire measures of anxiety. However, parent-report data indicated that there was a positive treatment effect of CBT on autism symptom severity. The CBT manual under investigation, enhanced for early adolescents with ASD, yielded meaningful treatment effects on the primary outcome measure (PARS), although additional developmental modifications to the manual are likely warranted. Future studies examining this protocol relative to an active control are needed. (PsycINFO Database Record (c) 2016 APA, all rights reserved)

Child Psychiatry and Human Development. 10.1007/s10578-011-0238-1
We compared the effects of a 16-week Cognitive-Behavioral Therapy (CBT) program and a Social Recreational (SR) program on anxiety in children with Autism Spectrum Disorders (ASD). Seventy children (9–16 years old) were randomly assigned to either of the programs (nCBT = 36; nSR = 34). Measures on child’s anxiety using the Spence Child Anxiety Scale—Child (SCAS-C) and the Clinical Global Impression—Severity scale (CGI-S) were administered at pre-, post-treatment, and follow-ups (3- and 6-month). Children in both programs showed significantly lower levels of generalized anxiety and total anxiety symptoms at 6-month follow-up on SCAS-C. Clinician ratings on the CGI-S demonstrated an increase in the percentage of participants rated as ‘‘Normal’’ and ‘‘Borderline’’ for both programs. Findings from the present study suggest factors such as regular sessions in a structured setting, consistent therapists, social exposure and the use of autism-friendly strategies are important components of an effective framework in the management of anxiety in children and adolescents with ASD.

Objective: This study compared family-focused cognitive behavioral therapy (CBT; the Building Confidence Program) with traditional child-focused CBT with minimal family involvement for children with anxiety disorders. Method: Forty clinically anxious youth (6-13 years old) were randomly assigned to a family- or child-focused cognitive-behavioral therapy (CBT). Conditions were matched for therapist contact time. Both interventions included coping skills training and in vivo exposure, but the family CBT intervention also included parent communication training. Independent evaluator, parent, and child report measures with demonstrated validity and reliability were used to assess child anxiety symptom outcomes at pre- and posttreatment. The data analytic strategy involved an evaluable patient analysis. Results: Compared with child-focused CBT, family CBT was associated with greater improvement on independent evaluators’ ratings and parent reports of child anxiety–but not children’s self-reports–at posttreatment. Conclusions: Both treatment groups showed improvement on all outcome measures, but family CBT may provide additional benefit over and above child-focused CBT. These findings provide preliminary support for the efficacy of the ‘Building Confidence’ program and encourage further research in parental participation in treatment for childhood anxiety.

This study assessed the effectiveness of a combined individual and group cognitive-behavioural treatment (CBT) program to reduce music performance anxiety (MPA) in adolescent musicians. Twenty-three adolescents with high MPA from a selective high school were randomly assigned to either a seven-session intervention program or a behaviour-exposure-only control group. The intervention consisted of psychoeducation, goal setting, cognitive restructuring, relaxation training and behavioural exposure in the form of two solo performances with audience. Outcome measures included self-reports of MPA, trait and state anxiety, diagnostic interview for social phobia, heart rate, frontalis EMG, and performance quality. Significant improvements in self-reported MPA were observed at posttest for adherent students only (i.e., students who were actively engaged in the program and who adopted program techniques). Adherent students also had higher MPA at commencement. Non-adherent and behaviour-exposure-only students both showed reductions in MPA over the study period but not to the same degree as adherent students. There appeared to be no effect of CBT on performance quality. (PsycINFO Database Record (c) 2018 APA, all rights reserved)

Despite prevalence rates as high as 9.4%, few studies have examined the applicability of cognitive-behavioral therapy for treatment of anxiety disorders in very young children (i.e., below the age of 7 years). The present study examined the preliminary efficacy of a parent-led exposure therapy protocol (PLET) designed for young children with anxiety disorders. Twenty-two youth aged 4–7 years and their parents participated in this pilot randomized control trial. Families of youth with significant anxiety concerns were randomized to either PLET (n = 12), a 10 session/5-week family-based exposure therapy program designed to target anxiety in young children, or treatment as usual (TAU; n = 10). Children in the PLET condition demonstrated a greater reduction in anxiety symptoms compared to TAU (d = 3.18), with 90.91% of PLET participants (active condition) being classified as treatment responders at post-treatment as opposed to 0 in the TAU condition. Gains were maintained at 1 month-follow-up. Although pilot in nature, these data suggest in a preliminary fashion that a parent led exposure therapy protocol that is adapted appropriately for developmental age and incorporates an active coaching component for parents may be efficacious for the treatment of young children with anxiety disorders.

Evaluated the feasibility and effectiveness of a school-based group cognitive-behavioral treatment (CBT) for anxiety disorders with African-American adolescents. Twelve adolescents (mean age = 15.6 years) with anxiety disorders were randomly assigned to CBT (n = 6) or a group attention-support control condition (AS-Control; n = 6). Both groups met for 10 sessions in the same high school. Key treatment ingredients in CBT involved exposure, relaxation, social skills, and cognitive restructuring. Key ingredients in AS-Control involved therapist and peer support. At preand posttreatment, diagnostic interviews were conducted, and adolescents completed self-report measures of anxiety. At posttreatment and among those who attended more than one treatment session, 3/4 adolescents in CBT no longer met diagnostic criteria for their primary anxiety disorder, compared with 1/5 in AS-Control. Clinician ratings of impairment and self-report levels of overall anxiety were significantly lower at posttreatment in CBT compared with ASControl. Teenagers in both groups reported lower levels of social anxiety from pre- to posttreatment. Findings support the feasibility of implementing a manual-based CBT in an urban school setting.

This preliminary randomized controlled trial (RCT) examines the feasibility of dismantling cognitive behavioral therapy (CBT) for childhood anxiety disorders. Fourteen children (10 girls) ages 7 to 14 (m = 10.2) with social phobia, generalized anxiety disorder, separation anxiety disorder, or panic disorder were randomized to receive 6 sessions of either a) the pre-exposure anxiety management strategies presented in traditional CBT, or b) parent-coached exposure therapy. The sample was selected from a treatment seeking population and is representative of children in clinical settings. Examination of fidelity ratings, dropouts, and satisfaction ratings indicated that the interventions were distinguishable, safe, and tolerable. The overall sample improved significantly with pre-post effect sizes generally in the large range for both conditions. Between-group effect sizes indicating greater improvement with parent-coached exposure therapy were moderate or large for ten of 12 variables (i.e., 0.53 to 1.52). Re-evaluation after three months of open treatment suggested that the intervention emphasizing exposure early maintained its superiority while requiring fewer appointments.

Journal of Child Psychology and Psychiatry. 10.1111/1469-7610.00659
50 children (aged 7–14 yrs) with a principal diagnosis of social phobia were randomly assigned to either child-focused cognitive-behavior therapy (CBT), CBT plus parent involvement, or a wait list control (WLC). The integrated CBT program involved intensive social skills training combined with graded exposure and cognitive challenging. At posttreatment, significantly fewer children in the treatment conditions retained a clinical diagnosis of social phobia compared to the WLC condition. In comparison to the WLC, children in both CBT interventions showed significantly greater reductions in children’s social and general anxiety and a significant increase in parental ratings of child social skills performance. At 12-mo follow-up, both treatment groups retained their improvement. There was a trend towards superior results when parents were involved in treatment, but this effect was not statistically significant. (PsycINFO Database Record (c) 2016 APA, all rights reserved)

Background: The effectiveness of cognitive-behavioral treatment (CBT) in inner city schools, when delivered by novice CBT clinicians, and compared to usual care (UC), is unknown. Objective: This pilot study addressed this issue by comparing a modular CBT for anxiety disorders to UC in a sample of 32 volunteer youth (mean age 10.28 years, 63% female, 84% African American) seen in school-based mental health programs. Methods: Youth were randomly assigned to CBT (n = 17) or UC (n = 15); independent evaluators conducted diagnostic interviews with children and parents at pre- and post-intervention, and at a one-month follow-up. Results: Based on intent-to-treat analyses, no differences were found in response rates between groups with 50 and 42% of the children in CBT, compared to 46 and 57% in UC no longer meeting criteria for an anxiety disorder at post-treatment and follow-up respectively. Similar improvements in global functioning were also found in both treatment groups. Baseline predictors of a positive treatment response included lower anxiety, fewer maladaptive thoughts, less exposure to urban hassles, and lower levels of parenting stress. Therapist use of more CBT session structure elements and greater competence in implementing these elements was also related to a positive treatment response. Conclusions: Findings from this small pilot failed to show that CBT was superior to UC when delivered by school-based clinicians. Large scale comparative effectiveness trials are needed to determine whether CBT leads to superior clinical outcomes prior to dissemination.

BACKGROUND: Children with pain-related functional gastrointestinal disorders (P-FGIDs) have an increased risk for school absenteeism, depression, anxiety and low quality of life. Exposure-based cognitive behavior therapy (CBT) has shown large treatment effects in adults with irritable bowel syndrome, but has not been tested for children 8-12 years with P-FGIDs. AIM: The aim of this trial was to test the feasibility, acceptability and potential efficacy of a newly developed exposure-based CBT for children with P-FGIDs. METHOD: The children (n = 20) with a P-FGID, were referred by their treating physicians. The participants received 10 weekly sessions of exposure-based CBT and were assessed at pre-treatment, post-treatment and 6-month follow-up. RESULTS: Children improved significantly on the primary outcome measure pain intensity at post (Cohen’s d = 0.40, p = 0.049) and at 6-month follow-up (Cohen’s d = 0.85, p = 0.004). Improvements were also seen in pain frequency, gastrointestinal symptoms, quality of life, depression, anxiety, school absenteeism and somatic symptoms. Improvements were maintained or further increased at 6-month follow-up. The children engaged in the exposures and were satisfied with the treatment. CONCLUSIONS: Exposure-based CBT for children with P-FGIDs is feasible, acceptable and potentially efficacious.

Chu BC and Crocco ST and Esseling P and Areizaga MJ and Lindner AM and Skriner LC (2016 Jan) Transdiagnostic group behavioral activation and exposure therapy for youth anxiety and depression: Initial randomized controlled trial.. Behaviour research and therapy. 10.1016/j.brat.2015.11.005 [doi], S0005-7967(15)30054-1 [pii]
Anxiety and depression are debilitating and commonly co-occurring in young adolescents, yet few interventions are designed to treat both disorder classes together. Initial efficacy is presented of a school-based transdiagnostic group behavioral activation therapy (GBAT) that emphasizes anti-avoidance in vivo exposure. Youth (N = 35; ages 12-14; 50.9% male) were randomly assigned to either GBAT (n = 21) or WL (n = 14) after completing a double-gated screening process. Multi-reporter, multi-domain outcomes were assessed at pretreatment, posttreatment, and four-month follow-up (FU). GBAT was associated with greater posttreatment remission rates than WL in principal diagnosis (57.1% vs. 28.6%; X1(2) = 2.76, p = .09) and secondary diagnosis (70.6% vs. 10%; X1(2) = 9.26, p = .003), and greater improvement in Clinical Global Impairment - Severity ratings, B = -1.10 (0.42), p = .01. Symptom outcomes were not significantly different at posttreatment. GBAT produced greater posttreatment behavioral activation (large effect size) and fewer negative thoughts (medium effect), two transdiagnostic processes, both at the trend level. Most outcomes showed linear improvement from pretreatment to FU that did not differ depending on initial condition assignment. Sample size was small, but GBAT is a promising transdiagnostic intervention for youth anxiety and unipolar mood disorders that can feasibly and acceptably be applied in school settings.

Journal of consulting and clinical psychology. 10.1037/a0038402 [doi]
OBJECTIVE: To evaluate changes in the trajectory of youth anxiety following the introduction of specific cognitive-behavior therapy (CBT) components: relaxation training, cognitive restructuring, and exposure tasks. METHOD: Four hundred eighty-eight youths ages 7-17 years (50% female; 74% </= 12 years) were randomly assigned to receive either CBT, sertraline (SRT), their combination (COMB), or pill placebo (PBO) as part of their participation in the Child/Adolescent Anxiety Multimodal Study (CAMS). Youths in the CBT conditions were evaluated weekly by therapists using the Clinical Global Impression Scale-Severity (CGI-S; Guy, 1976) and the Children’s Global Assessment Scale (CGAS; Shaffer et al., 1983) and every 4 weeks by blind independent evaluators (IEs) using the Pediatric Anxiety Ratings Scale (PARS; RUPP Anxiety Study Group, 2002). Youths in SRT and PBO were included as controls. RESULTS: Longitudinal discontinuity analyses indicated that the introduction of both cognitive restructuring (e.g., changing self-talk) and exposure tasks significantly accelerated the rate of progress on measures of symptom severity and global functioning moving forward in treatment; the introduction of relaxation training had limited impact. Counter to expectations, no strategy altered the rate of progress in the specific domain of anxiety that it was intended to target (i.e., somatic symptoms, anxious self-talk, avoidance behavior). CONCLUSIONS: Findings support CBT theory and suggest that cognitive restructuring and exposure tasks each make substantial contributions to improvement in youth anxiety. Implications for future research are discussed. (PsycINFO Database Record

Neurobiological studies have demonstrated that psychotherapy is able to alter brain function in adults, however little exists on this topic with respect to children. This waiting-list controlled investigation focused on therapy-related changes of the P300 and the late positive potential (LPP) in 8- to 13-year-old spider phobic girls. Thirty-two patients were presented with phobia-relevant, generally disgust-inducing, fear-inducing, and affectively neutral pictures while an electroencephalogram was recorded. Participants received one session of up to 4h of cognitive-behavioral exposure therapy. Treated children showed enhanced amplitudes of the LPP at frontal sites in response to spider pictures. This result is interpreted to reflect an improvement in controlled attentional engagement and is in line with already existing data for adult females. Moreover, the girls showed a therapy-specific reduction in overall disgust proneness, as well as in experienced arousal and disgust when viewing disgust pictures. Thus, exposure therapy seems to have broad effects in children.

Blatter-Meunier J and Schneider S (2011) [Separation anxiety family therapy (SAFT): a cognitive behavioral treatment program for children suffering from separation anxiety].. Praxis der Kinderpsychologie und Kinderpsychiatrie. NA
Separation Anxiety Disorder is one oft the most frequent mental disorders in children. The SAFT treatment manual is an evidence-based cognitive behavioral therapy program for children with separation anxiety. Its first part consists of four weekly sessions with the child and four weekly sessions with the parents. Children and parents receive psychoeducation about anxiety, learn to recognize and reframe irrational beliefs about separation situations, expand their repertoire of coping strategies, and are introduced to the rationale for exposure. The second part of treatment consists of eight weekly family sessions followed by a short parent-only session. During the family sessions, exposure in vivo is planned and practiced. The parent-only portions of the family sessions involve reframing parental irrational beliefs about separation, parenting strategies and practicing parental behavior during exposure. Evaluation data shows that disorder-specific family-based therapy (SAFT) results in improvement compared with waiting list controls.

The present study compared the efficacy of trauma-focused cognitive behavior therapy (CBT) with trauma-focused cognitive therapy (without exposure; CT) for children and youth with posttraumatic stress disorder (PTSD). Children and youth who had experienced single-incident trauma (N = 33; 7-17 years old) were randomly assigned to receive 9 weeks of either CBT or CT which was administered individually to children and their parents. Intent-to-treat analyses demonstrated that both interventions significantly reduced severity of PTSD, depression, and general anxiety. At posttreatment 65% of CBT and 56% of the CT group no longer met criteria for PTSD. Treatment completers showed a better response (CBT: 91%; CT: 90%), and gains were maintained at 6-month follow-up. Maternal depressive symptoms and unhelpful trauma beliefs moderated children’s outcome. It is concluded that PTSD secondary to single-incident trauma can be successfully treated with trauma-focused cognitive behavioural methods and the use of exposure is not a prerequisite for good outcome.

OBJECTIVE: The aim of this research project is to investigate the effects of cognitive-behavioral group therapy on adolescents suffering from symptoms of social anxiety. METHOD: cognitive behavioral group therapy program for reducing social anxiety was developed by the authors, after which a pilot study was conducted, evaluated for deficiencies, finalized, and implemented in the following study. The final program entailed 13 sessions covering relaxation training, cognitive restructuring and exposure components. To recruit the participants for the intervention program screening tests were applied to 711 students of three different junior high schools in Izmir. 44 students (treatment=24, control= 20) who met the inclusion criteria in the seventh and eighth grades participated in the main study. Evaluation of the therapy program was ascertained using the following instruments; for students, Negative Cognitive Errors Questionnaire (CNCEQ), Cape Social Phobia Scale for Children and Adolescents (CSPSCA), Social Anxiety Scale for Adolescents (SAS-A); and for parents, (SAS-P) was used to compare their pre-program and post-program tests results. RESULTS: Repeated measures ANOVAs yielded significant Group X Time interactions for SAS-A (F (1, 42) =7.511, p< 0.01, eta2 =0.15), CSPSCA (F (1, 42) =6.54, p<.05) and CNCEQ (F (1, 42) = 8.295, p<0.01, eta2 =0.16) scores. Results from parents further indicated that social anxiety in the treatment group had decreased after program completion (F (1, 42) = 9.496, p=0.004, eta2 =0.18). CONCLUSION: Consistent with the literature of school based Cognitive-Behavioral Group Treatment (CBGT) programs for social anxiety, it was found that adolescents in the treatment group exhibited a significant decrease in social anxiety and related cognitive errors.

Kendall PC and Flannery-Schroeder E and Panichelli-Mindel SM and Southam-Gerow M and Henin A and Warman M (1997 Jun) Therapy for youths with anxiety disorders: a second randomized clinical trial.. Journal of consulting and clinical psychology. NA
Ninety-four children (aged 9-13 years) with anxiety disorders were randomly assigned to cognitive behavioral treatment or waiting-list control. Outcomes were evaluated using diagnostic status, child self-reports, parent and teacher reports, cognitive assessment and behavioral observation: maintenance was examined using 1-year follow-up data. Analyses of dependent measures indicated significant improvements over time, with the majority indicating greater gains for those receiving treatment. Treatment gains returned cases to within nondeviant limits (i.e., normative comparisons) and were maintained at 1-year follow-up. Client age and comorbid status did not moderate outcomes. A preliminary examination of treatment segments suggested that the enactive exposure (when it follows cognitive-educational training) was an active force in beneficial change. Discussion includes suggestions for future research.

We will use a metabefor extraction script for the extraction of the data. The idea of this script is to extract the data from the original sources with a minimum of interpretation. The data is extracted into a machine-readable format, which then allows competely transparent further processing and synthesis.
These scripts are generated on the basis of two tables/spreadsheets. The first contains the entities to extract, such as study year, sample size, how variables were operationalised, and associations that were found. The second contains the valid values for each entity, to allow efficiently providing coders with examples, instructions, and to allow easy verification of the input.

Ik ben geen expert op dit gebied, maar ik hoop voor je analyse dat uitkomstmaten te vergelijken zijn voor beide theorieeen. Habituatie is veelal ouder, dus daar worden misschien niet alleen andere proximale maten gebruikt, maar ook bijv. DSM criteria komen uit een eerdere DSM versie dan de meer recente studies over inhibitie.
Presumably you have already gone through the papers by Michelle Craske on maximising exposure therapy.
